Let’s get to know about data transfer first
Before discussing the Aruba 2930M product in more detail, it would be nice for us to know about data and data transfer so that we can better understand the functions of Aruba’s switch products.
Explanation About Data
Data comes from the Latin word datum which means something that is given. Data is a collection of information or information obtained from the results of information or observations in the form of symbols, numbers or characteristics.
Data definitions
Data is a statement that is accepted as it is without being exaggerated or reduced. Or it can also be interpreted as data that can be obtained from various sources which become an assumption or fact because it has not been processed further.
data function
The function of the data itself is as information for the recipient, data can also have other functions, namely as a basis for a plan, a control tool for the implementation or also the implementation of an activity, and a decision-making tool. In general, the function of data is as a basis for evaluating an activity.
Types of data based on the source
Types of data that can be shared based on the source include:
internal data
This data is generally obtained from an organization or institution where the research was carried out. For example, a lecturer who conducts research on lecturer performance and all aspects that influence it.
External data
This type of external data was obtained from other institutions or organizations where the research was conducted.
For example, researchers want to know the business growth of an MSME product. This researcher is looking for information outside the company concerned, such as at the Central Bureau of Statistics (BPS). Well, this information is referred to as external information.
Data Transfer Speed
Data transfer speed is the number of data packets that can be sent or received by a computer in a unit of time.
In sending data, the computer will add 1 bit in front as the beginning of the data and 1 bit to the end of the data, so that each character is 10 bits.
For example, the modem speed is 28,000 bps, which means that the modem can pass as much as 2,800 data, which is 28,000/10 characters every second.
Computers are known as bit units, namely binary digits or binary numbers. So that 1 bit is equal to 1 character per letter in the binary number system. A data packet usually consists of several bits depending on the system used.
In general, the data packet units that are often used in computers are as follows:
1 byte = 8 bits = 1 character
1 KB = 1 kilobytes = 210 bytes = 1024 bytes
1 MB = 1 Megabytes = 220 bytes = 1,048,576 bytes
1 GB = 1 Gigabyte = 230 bytes = 1,073,741,824 bytes
Factors Affecting Data Transfer Speed
As for the factors that affect the speed of data transfer in an electronics. The five aspects include:
Data Transfers
Computers that are used to use the internet have important components including RAM, Processor, Hard disk, LAN Card or WiFi.
Modem
This modem has an influence on internet speed that varies for each specification of the device itself.
Network
This network is accessible to the internet and some of the services that can affect it. For example, namely telephone line services, GPRS, satellite or fiber optic.
Bandwidth
This bandwidth is the width or width of the frequency band that is in the signal or transmission medium. This bandwidth has an important role in the different access speeds for each ISP or Internet Service Provider, this bandwidth is measured in Hertz units.
User
Users who use internet access in the network will affect internet speed. Because the internet is used simultaneously, it will have an impact on the availability of existing bandwidth.
Discussion Regarding Switches
After knowing what data is, we will discuss switch devices. Incomplete if there is a network without a switch device. Where the switch is useful to help exchange data.
PC networks require tools to help exchange data. One that is often used is the switch. In a LAN system, this device is in the form of a box with many ports connected to each other.
Now, for friends who are still confused about what a switch is and its uses, here we present a full review for all of you.
Definition of Switches
The definition of a switch is a computer network device that plays a role in connecting high-speed computers to exchange data.
The switch will receive data from a source such as a server and then forward it to the device requesting the data. Conversely, hubs can also receive all data but distribute it to connected devices as recipients.
In simple terms, this switch is also defined as a connector device to a computer network that can forward data from one device to another.
Apart from switches, there are other tools that have similar strengths and uses, namely hubs. The next two devices even look similar, namely many ports. You must be aware of the differences between hubs and switches so that you can easily understand how they work, types, and functions.
Switch function
The switch function is a link between network devices to be able to communicate data with each other. There are several points of the switch function that you can see below.
Connector Device
The main switch function is as a connector. On a computer network you may need this tool to connect to devices, servers, routers and what have you. In addition, this switch can assist in managing communication networks so that data exchange can take place quickly.
Data Management
In addition to connectors, switches can also be used as data management. All of which will be immediately processed to ensure there are no errors. And also this tool delivers to devices that need it based on the MAC address and IP address.
Repeater Device
A repeater is a signal amplifier. Where data and signals from sources are very weak, the repeater will strengthen the signal.
Looping Avoidance
Looping avoidance is the ability to prevent data loops on switch ports.
An example is when a computer sends data that the destination of the recipient is unknown. So that the switch will forward to a certain MAC address by blocking ports on other devices.
Address Learning
Managed switches can also be used as address learning which can record MAC addresses between computer devices connected to one network.
When data transmission occurs, the switch will automatically record the MAC address of the sender and continue sending the appropriate data.
Validators and filters
Managed switch that checks whether the incoming data is valid and selects as needed. If it’s not enough then don’t send it to other devices. Users can identify directly whether the server and other computers that are sending data are correct or not.
Type Type Switch
Switches on the market do have their own variations. Usually the most common switch is differentiated based on its position and function in the network.
Layer 2 switches
Layer 2 switches are connectors from one device to another. Direct data exchange wear mac address for identification. This type is used for LAN, home and office networks that do not require large coverage. For example, the device is an 8-port hub switch. Each port will connect to other devices directly.
Layer 3 switches
Layer 3 switches can be implemented at the wider internet level. The use of MAC is no longer efficient because it has to send data to many ports. For example, you access the server to open a certain website. What is used for identification is not the MAC address but the IP address.
Unmanaged Switches
Unmanaged switch is a device that cannot be configured. Yes, it is true that this switch cannot be configured, it can only be used as a data transfer according to its default settings.
Managed Switches
Meanwhile, the managed switch configuration can be changed according to our needs. One of the advantages of this switch is that if an error occurs, it can be fixed easily compared to an unmanaged switch, which we cannot configure.
Ethernet Switches
An Ethernet switch is a device that can run at the data link layer of the OSI reference model. This Ethernet switch can support large amounts of data transfer over a network that is connected between computers.
ISDN switches
ISDN is the development of an IDN telephone network that can provide existing digital connections from one device to another.
Modular Switches
This modular switch is a type of switch that can increase the security of cables such as fiber optics and also their tidiness. Yes, it’s true that these modular switches usually have relatively more expensive prices than ordinary switches.
Smart Switches
Smart switches are developments in switch technology that offer multiple management and segmentation, quality of service, and security capabilities, making them a less expensive alternative to modular switches.
Cara Kerja Switch
Cara kerja switch ini memang cukup mudah dipahami karena merupakan alat fisik. Misalnya Anda dapat membuat jaringan yang terdiri dari satu server yang ada tiga komputer sebagai pengguna.
Alat ini dapat dipasang bagian sedang sebagai konektor server ke user. Saat server mengirim data, penerima bukan seluruh user melainkan user spesifik dan yang lain tidak berpengaruh.
Data Transfer Technology On Switch
Data transfer technology on this switch is divided into several points, among others.
ATM Switch (Asynchronous Transfer Mode)
Asynchronous Transfer Mode is the first technology of the switch. Data transfers are carried out asynchronously, where the recipient and sender do not have to have a synchronized time.
The role of switches in this technology can move various types of traffic such as voice, video, data, and others quickly and efficiently. This circuit switching usually requires that this packet is set to a position in the repeat frame.
STM Switch (Synchronous Transfer Mode)
STM switch is a process of sending data where the sender and receiver are in the same settings and at the same time with the aim that data can be sent and received properly by both computer devices.
Advantages and Disadvantages of Switches
How it works and functions, the next stage is a discussion of the advantages and disadvantages of using switches. You can find out more before deploying as well install the device on the network.
Advantages
The advantage of the switch lies in its ability to send data to connections that need it. Data exchange occurs on the needy. This way of working makes the switch more efficient and flexible.
Deficiency
Disadvantage of the switch is that it takes extra effort for settings. In addition, the price on the market is more expensive from the hub. Next, you will have to spend some money for a complex network. If the settings are wrong, it takes time to repair.
